Factors Influencing Vaccine Receipt During a 2018 Pediatric Typhoid Conjugate Vaccine Campaign in Navi Mumbai, India

In 2018, the Navi Mumbai Municipal Corporation implemented phase 1 of a public sector typhoid conjugate vaccine campaign in Navi Mumbai, India, targeting all children aged 9 months to 14 years within its administrative boundaries. To assess associations with receipt of vaccine in phase 1, we used generalized estimating equations to calculate estimates of vaccination by child-, household-, and community-level demographics (child education and age; household head education, income, and occupation; community informal settlement percent). Campaign vaccine receipt was most associated with children enrolled in school (odds ratio [OR] = 3.84, 95% CI: 2.18–6.77), the lowest household income tertile when divided into three equal parts (OR = 1.64, 95% CI: 1.43–1.84), and lower community-level socioeconomic status (OR = 1.06, 95% CI: 1.04–1.08 per 10% informal settlement proportion). The campaign was successful in reaching the most underserved populations of its target communities.
